Title: Knut Scheffler: Innovator in Radioactive Waste Management
Introduction
Knut Scheffler is a notable inventor based in Eggenstein-Leopoldshafen, Germany. He has made significant contributions to the field of radioactive waste management, holding a total of 2 patents. His innovative methods focus on solidifying aqueous radioactive wastes, ensuring safe and non-contaminating storage.
Latest Patents
Scheffler's latest patents include a method for solidifying high and medium radioactivity and/or actinide-containing aqueous waste concentrates. This method involves evaporating waste concentrates to achieve a water content between 40 and 80 percent by weight. The solid content, which consists of metal ions and/or metal oxides, ranges from 10 to 30 percent by weight of the evaporate. The pH of the evaporate is maintained between 5 and 10. The resulting evaporate is pelletized using a clay-like substance, followed by heat treatment at various temperatures to form practically undissolvable mineral phases. The pellets are then enclosed in a dense, continuous ceramic or metallic matrix, ensuring their stability and safety.
